For Linux and Windows, extract in $path_to_qtcreator$/lib/qtcreator/plugins/ and you should be good to go.For Mac OS X, extract in e.g. /Applications/Qt Creator.app/Contents/PlugIns/ Note that if Qt Creator is complaining at startup about wrong version numbers (patch number, not major or minor) for the plug-in dependencies, editing the Doxygen.pluginspec file and replacing the wrong version numbers should be enough to get it working.

Building project documentation: CTRL+SHIFT+F4 and the "Tools/Doxygen" menu -> "Build Doxygen Documentation".If you didn't create and configure a Doxyfile at your project root, the default one will be generated and used.

Edit Doxyfile with doxywizard: CTRL+SHIFT+F6

Don't forget to configure the "doxygen" and "doxywizard" commands in "Settings/Documentation/Doxygen Plugin" if it is not in your $PATH.

If you want latest source: grab an archive of the trunkIf you want a specific revision, then either select it manually on websvn or append &rev=$rev_number to the download link, e.g. for the source for qtcreator-2.0.1:

Pass arguments to qmake (revision r34 and up):QTC_SOURCE_DIR: The directory containing qtcreator source codeQTC_BUILD_DIR: The directory where we build the pluginLIBSROOT: The root of the built qtcreator lib directoryDEST: The directory where the shared library and the plugin spec files will be moved to
